Cecilia: An Amazing Front End For CSound-Version 4.2 for OSX & Windows

Cecilia is an audio signal processing environment using Csound as its audio engine. Cecilia lets you create your own GUI (grapher, sliders, toggles, popup menus) using a simple syntax. Cecilia comes with many original builtin modules for sound effects and synthesis. Previously written in tcl/tk, Cecilia was entirely rewritten in Python/wxPython and uses the Csound API for communicating between the interface and the audio engine. Version 4.2 beta is the current release.
